Scientists Identify Mysterious “Burtele Foot”

Scientists have resolved the mystery surrounding the 3.4 million-year-old fossils known as the “Burtele Foot,” discovered in Ethiopia in 2009. The fossils have now been identified as belonging to the species Australopithecus deyiremeda, a little-known human ancestor.

• New Fossil Evidence Leads to Breakthrough: The conclusion follows the recent discovery of 25 teeth and the jawbone of a 4½-year-old child near the original site. These new fossils matched the features of A. deyiremeda, first identified only a decade ago.

• Unique Mix of Human and Ape Traits: The Burtele Foot, found in Ethiopia’s Afar region, shows a combination of characteristics:

• The species was bipedal, walking on two legs.
• It possessed an opposable big toe, useful for climbing, indicating a different style of upright walking compared to modern humans.
• The anatomy reveals a blend of ape-like agility and human-like locomotion.

• Coexistence of Two Hominin Species: The discovery shows that Australopithecus deyiremeda lived in the same region and period as Australopithecus afarensis, the species that includes the famous fossil Lucy. This coexistence raises evolutionary questions about:

• Whether they competed for the same resources.
• Or whether their differing traits allowed them to avoid direct competition.

• Insight into a Critical Evolutionary Period: These findings add significant depth to knowledge of human evolution during a poorly understood era, millions of years before Homo sapiens emerged around 300,000 years ago.

The study was published in Nature.
